Microhydro system /off grid
My Question:
I want to use a 1000 gal tank on top of my house 30ft, water from tank into hydro out into small reservoir or pipe use a small pump to send water back into tank continuous. Is that   viable in cost for Jamaica?  Diesel expensive in Jamaica, wind and solar, but prefer hydro while not close to stream.

Donald,

Hydro systems only work if you have a "free" continuous supply of water. Unless you have a perpetual motion machine, you will be using more energy to pump the water back into the tank than you will get from it.

Old fashioned lead acid batteries are still the most economical method of storing any excess energy that you produce, and I think they only return about 80% of what you put into them.

What exactly are you trying to achieve with renewable energy?

I want to charge my battery with the hydro system, and since I do not have a stream I want to use a 1000 gal thank to run the system.
